    <div class="form-group form-group-label">
        <div class="row">
            <div class="col-md-10 col-md-push-1">
                <label class="floating-label" for="login-username">Title</label>
                <form:input path="title" cssClass="form-control"/>
            </div>
        </div>
    </div>
    <div class="form-group form-group-label">
        <div class="row">
            <div class="col-md-10 col-md-push-1">
                 <form:checkboxes items="${bars}" path="bars" cssClass="form-control" itemValue="id" itemLabel="name"/>

            <span class="circle"></span>
            <span class="circle-check"></span>
